Frequency pre-compensation for high-speed train single frequency networks

A method of wireless communications, comprising:

• receiving, by a user equipment (UE) on a single frequency network (SFN), a configuration associated with a frequency pre-compensation for use by a transmission and reception point (TRP);
• receiving, by the UE, a signal modified by the frequency pre-compensation;
• and
• performing, by the UE, channel estimation of the signal based on the configuration.

A base station, comprising:

• a memory;
• a transceiver;
• and
• a processor coupled with the memory and the transceiver and configured, when executing instructions stored on the memory, to cause the base station to:
• determine a frequency pre-compensation for a transmission and reception point (TRP) on a single frequency network (SFN);
• transmit to a user equipment (UE) a configuration associated with the frequency pre-compensation via the TRP;
• and
• apply the frequency pre-compensation to a signal for transmission by the TRP to the UE.
